chocolate brownie

at our favorite zoo, there are four alpacas that we feed every time we go. actually, we just feed two of them because the other two are in a separate pen and one of them likes to spit so we avoid that area! anyway, the two we feed are named Biff and Charlie Brown. but caleb doesn't call the second one charlie brown, he calls him "chocolate brownie." he's so set on this, for some reason, that once when i said "sorry charlie" to him, he replied back with "sorry chocolate brownie!"
